Find the area of the shaded segment use pi key on your calculator to approximate pi round your answer to the nearest tenth

well, AO and OB are both radii, and therefore, both of them are 10 inches long, meaning the triangle has a height of 10 and a base of 10.

let's also bear in mind that the central angle of that segment as well as sector is 90°.

so a parallelogram is just like a square base times height. multiply 40 and 39 to get 1560 inches.

a triangle is base times height divided by two. so multiply 7.9 and 5 and then divide it by 2 to get 19.75inches.

the kite can be split into two separate triangles and added together to get the total area. 30 x 4 /2 which equals 60. make sure to double it for the two triangles making 120.

you can use a^2+ b^2=c^2
